General Description

The LPA2100 are mono efficient, digital amplifier power stage for driving speakers up to 25W/4Ω. The LPA2100 integrates AGC(automatic gain control)circuit for a NCN(Non-Crack Noise) technical in application without damaging speaker when a high power signal occurs. when function failed happened to input capacitor, the chip will cut off the output circuit through detecting the input signal to protect speaker. The LPA2100 device is fully protected against faults with short-circuit protection and thermal protection as well as over-voltage and DC protection. Faults are reported back to the processor to prevent devices form being damaged during overload conditions.
